cz jewelry wholesale suppliers in india These are diamond 4C
The 4C classification of diamonds refers to:
N
The source of weight cact
4c means that the first letters in the above four English words are "C", so people's grades of diamonds are referred to as 4C grading or 4C assessment. At present, it is global pair Diamond grading general standards.
This customers may ask which "C" when evaluating diamonds is more important?
In fact, at the 4C assessment, each element is very important, which plays a key role in the final price of the diamond finished product. In the case of near other elements, the most important thing is the total amount of diamonds. The larger the diamonds, the thinner and the scarce. Therefore, determining the price of a diamond, which weighs more important position, is also the reason why customers are usually commonly seen to measure prices.
wholesale custom initial jewelry The value of diamond ring is mainly diamond
The value of diamonds is 4C.
The weight unit is carat, one carat = 100 points = 0.2 grams
The cut contains the platform width, the depth of the pavilion, etc., polishing and symmetrical.
The color level from high to low is d, e, f, g, h, i, j. Essence Essence
The clarity level from high to low is FL, IF, VVS, VS, SI

"4C" is the measurement standard for you to judge the value and quality of a diamond. The so -called "4C" is the abbreviation of four English words starting with C. It refers to the caraat weight, clarity, color, and cut (CUT). Just comprehensively appreciate the four points of "4C", you can easily understand the value and quality of a diamond. Diamond price = weight color clarity cutting.
diamond value
The value of diamonds can be identified by 4C parameters, except for the color diamond.
The diamond weight is calculated in carat (also known as card). 1 carat = 200 mg = 0.2 grams. One carat is divided into one hundred copies, each called one point. 0.75 carats are also called 75 points, and 0.02 carats are 2 points. Under other conditions, as the diamond weight increases, the value of the value is increased geometrically; diamonds with the same weight will be far from the difference in color, clarity, and cutting. In each different size and shape, you can find a high -quality diamond. The most important thing is to find a diamond that is suitable and style that makes you like. You might as well try in the jewelry shop. When it looks right and feels right, that one should be yours.
The clarity
The diamond crystals in the mantle magma deep in the earth. The environment is complicated, the composition is diverse, the temperature and pressure are extremely high, and after hundreds of millions of geological changes, the internal will inevitably contain a variety of debris or existence flaw. The color, how much, size, and position distribution of these inside contains the effects of different degrees on diamond clarity.
The clarity of diamonds usually uses 10 times large mirror to classify the clarity level of unlimited diamonds inside the diamond, surface flaw, and its impact on the degree of influence on gloriousness. , VS1, VS2, SI1, SI2, P1, P2, P3 in total 10 levels. The inlaid diamonds are divided into excellent, good, good, better, generally 5 levels. P -level diamonds are also called Class I diamonds. The following P -level diamonds are generally not used as gems, so they are generally only divided into P1/P2/P3.
The interpretation of IF, VVS, VS, SI, and P is commonly used internationally as:
(1) The perfect flaw in the country is LC, that is, it cannot be seen under ten times the magnifying glass. To defects -Remember: inlaid diamonds cannot be given to this level. ——The keep in mind: Domestic inlaid diamond grades cannot be given to this level.
(2) VVS is divided into VVS1 and VVS2. V = VERY, VVS -is a small (very very) small inner content -professional diamond grading division is also extremely difficult to find in the internal content of the needle tip of the needle under 10 times the large mirror.
(3) VS subdivisions are vs1 and VS2. VS levels are larger than VVS. It is difficult to find that professional diamond grades under 10 times mirror. VS2 levels are more than VS1. VS level is the dividing line of high -quality diamonds.
(4) Si is subdivided as SI1 and SI2, which are small flaws. It is easy to see defect SI1 under ten times to magnify the mirror. Essence Therefore, the naked eye above SI when purchasing diamonds cannot distinguish the difference.
The color
The diamonds have many natural colors, from precious colorless (white after cutting white), rare light blue, pink to common slightly yellow. The more transparent, the more white can penetrate, and the more colorful after refraction and color.
The diamond color grading is in the hierarchical environment of a professional laboratory. The technicians will be determined repeatedly with the standard color of the standard color than the standard color stones.
The whitening diamonds are set as D -episodes (that is, start with Diamond's first letter). The color of diamonds is divided into 11 levels, in turn: D, E, F, G, H, I, J, K, L, M, N.
Cutting
The cutting of diamonds refers to the accuracy of its cutting ratio and the perfection after the completion. Good cuts should be as good as possible to reflect the brightness and fire of diamonds as possible, and try to maintain the weight of the rough. GIA's cutting level from high to low is divided into ID (standard), EX (excellent), VG (good) G (good) G (good), Chinese national inspection is divided into: EX (excellent), VG (very good), G (g (very good), g it is good). The best cutting is the "eight hearts and eight arrows". It uses the world's top Cupid -style cutting, which is CEMNI's exclusive and original diamond cut. The perfect and symmetrical eight hearts and eight arrows are stunning.
In in China, ordinary people generally look at the size of the diamond. It is actually unscientific. Because China is more popular. Therefore, the more popular concept is high -quality glory diamonds. High -quality glory diamonds generally grasp the three principles of 4C: clarity, color (color), and cut (CUT), and the three standards must meet certain standards at the same time.
Overview
Rings
The clarity refers to the normal vision, trained diamond grading personnel under the source of artificial standard light of D55 or D65, and observe with ten times the magnitude of light difference and equivalent light. Diamond clarity characteristics from scratch.
It 10 times large mirror to observe the number of diamonds and surface defects, distribution, size, and the impact of diamond glory, which can be divided into LC, V v, vs, Si, P, a total of 5 large and 10 small grades.
The standard clause
LC (flawless level)
The experienced grades are observed with a large mirror at 10 times under the standard light source without finding any flaws. That is to say, the diamond does not contain any flaws that are greater than 5 microns and have sufficient brightness.
v v S1-V v S2 (extremely micro-flaw)
The experienced grades can find very small flaws with 10 times large mirror. It is difficult to be difficult. Determine whether it is V v S1 or V v S2 according to the size, location and quantity of the characteristics of defects.
VS1-VS2 (micro-flaw)
The experienced grades can find small flaws with 10 times large mirror. Its difficulty is

is not difficult. Determine whether it is VS1 or VS2 according to the size, location and quantity of the characteristics of defects.
SI1-SI2 (small flaw) experienced personnel can easily discover small flaws with 10 times large mirror. Determine whether it is SI1 or SI2 according to the size, location, and quantity of the characteristics of defects.
p1 (Xiaohua): Experienced grades are difficult to find the characteristics of defects from the crown of the diamond to observe the characteristics of the naked eye.
P2 (medium flower): Experienced hierarchical personnel are easy to find large and many flaws with the naked eye, which slightly affects the "fire" of diamonds.
P3 (big flower): Experienced grades are easy to find large and many flaws with the naked eye, which will greatly affect the "fire" of diamonds.
Igly
(1) The better the clarity of the diamond, the higher the price. When you want to buy a high clarity diamond
diamond ring
or for investment and collection, it is the most appropriate. When you have no special requirements for the clarity of diamonds, the choice of SI -level cost performance is the highest, and the naked eye cannot distinguish the SI and VS levels. Moreover, defects are part of the diamond, which is a unique label made by nature for each diamond.
(2) Buying a diamond ornament does not necessarily require VS and I levels. Diamonds embedded on the platinum support, the color reaches K color. For diamond ornaments below 0.25CT, especially bracelets, earrings, pendants, etc., do not have to demand color and clarity. As long as you work well, you can "fire" (referring to the big color of diamonds).
